A consideration on a stereo echo canceller using blind signal separation

A convectional stereo echo canceller had to stop updating parameters during the double talk. So, it has a problem for reliability of transmitted signals. In this paper, we propose a stereo echo canceller using blind signal separation method (BSS). In our proposed system, we remove echo signals by separating echo signals and speakers signals. So, it is not to need double talk processing. As a result, it has a high reliability of transmitted signals.
